In a series of tweets Saturday, the "Today" show meteorologist said he was trying to hail a cab with his 13-year-old son when he was passed by. Roker said the cab pulled up and he was reaching for the door when the driver took off and picked up a white passenger about a block away.

"Filed a complaint today after getting passed up again by a NYC Yellow cab. Cabbie picked up a white guy a block away. Wonder why Uber wins?" Roker said.

Roker tweeted he was trying to hail a cab to get "a sick kid to the dr." He said his son asked why the cab driver passed them over.

"I said, 'Nick, ignorant people make dumb choices,'" Roker tweeted. "This happens to folks of color every day. And while most cabbies do their job, there are those ignorant, racist ones who hurt the others."

"We're grateful that Mr. Roker took the time to file a complaint, and I can assure him that we will investigate this thoroughly and take every appropriate action," a spokeswoman for the commission said.
